I've been using OPK, so I know I spike around day 13 every month in a 28 day cycle. Other ladies on here told me that is not enough to tell if I am actually ovulating. It seems like every other month I have sore breasts, a little nausea, and a sorta bloated feeling in the 2ww. It's as different as night and day, and wondered if this could mean I'm not ovulating every month or if there is something wrong with my luteal phase. I am headed to the doc on May 5 for a consult... I'm wondering if it's an age thing, if others have experience on this, or if it's in my head!
